Stone anchor

ABSTRACT

A stone anchor for attachment between the face of a building and pieces of veneer such as stone. A threaded anchor stud carries an internally threaded collar which is attached to the flat plate that extends between joints in adjacent courses of stone. The flat plate may carry angular portions at the end which extend into kerfs formed in the respective adjacent stones. The end of the stud is inserted into a hole in the face of the wall and secured therein by mortar, adhesive and the like and thereafter the collar with the plate may be screwed in or out relative to the face of the wall to adjust the stone anchor to the proper extension thereby eliminating altogether the use of a variety of different sizes of stone anchors. In one form the plate is split on the end and turned in opposite directions whereas in another form a pin is secured perpendicularly to the plate.

2. Description of the Prior Art US. Pat. Nos. 938,662; 2,298,743;2,663,735; 3,178,026; 3,450,427; 3,471,183 may be considered relevantprior art. However, none of these patents disclose an adjustable stoneanchor. Significant prior art might be the information listed in theMarble Institute of America, Inc. AMERICAN STANDARD SPECIFI- CATIONS FORTHIN EXTERIOR MARBLE VE- NEER, ETC, copyrighted by the Marble Instituteof America in 1961, and also the Building Stonelnsfllte STONE 1968 69 CAI A IJO G w'lficli contains a Glossary of Terms stating that similartypes of anchors of flat stock are known as straps, cramps, dove tailsand dowel, strap and dowel and two-way anchors and discloses a number offorms of these none of which are stone anchors that are adjustable. Thestone anchors disclosed in the above material are fixed and notadjustable.

SUMMARY OF THE INVENTION By having the anchor member which is insertedand fixed into the wall adjustably supporting the part of the anchorwhich fits into the joint between the stone, it is possible afterinstallation of the fixed stone member to adjust the movable portioninwardly or outwardlythereby eliminating the cost of carrying manydifferent sizes of stone anchors and also the labor consumption on thejob of selecting the proper sizes. In addition, it is much easier toobtain the proper size because of the flexibility of adjustment.

' BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a cross-sectional view of aconcrete wall with the stone anchor of FIG. 3 installed therein.

, FIG. 2 is a perspective view of an adjustable stoneanchor of thepresent invention with a vertical pin.

FIG. 3 is a perspective view of another form of the present adjustableanchor utilizing turned ends.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 there is shown incross-section a typical installation of a bottom course of marble and aportion of the next adjacent course. A concrete wall of a buildingdesignated generally by reference numeral may be the usual pouredconstruction in a multi-story building. Such construction 10 usuallyinvolves an irregular concrete face 12 which is veneered by decorativestone shown in the drawing as two courses 14 and 16. The bottom course14 may be supported in conventional manner on a steel support angle 18which is attached to the surface 12 of the building 10 in anyconventional manner and usually has a vertical lugor pin 20 on the ledge22 thereof extending into a kerf 22 in the stone 14.

The adjustable stone anchor is designated generally by reference numeral26 and comprises a first member 28 which is usually a fixed member andis presently in the form of a threaded shaft having a head 30 like anail thereon, and a threaded portion 32 extending a substantial distancealong the shaft. A portion of the shaft 28 is inserted in a hole 34which has been drilled into the wall of the building 10 and secured inplace by any suitable adhesive 36 such as mortar or cement such asepoxy. The shaft 28 is arranged generally perpendicular to the wall 12,extends outwardly therefrom and carries a threaded collar 40 in a blockwhich is internally threaded or threadedly match with the threads 32 onshaft 28 and which collar 40 is integrally formed with or attached, asby welding, to a flat plate member 44 which extends between the joint 46of the adjacent courses of stone l4, 16. Plate 44 is split on the endand bent in opposite directions to form substantially perpendicular ends50, 52 each of which extends into a respective kerf 54, 56 formed in arespective stone 14, 16.. In some anchors the shaft member 28 is a flatpiece of V-shaped metal.

In the installation after the anchor 26 has been firmly fixed in thewall of the building 10 by the adhesive 36 then the plate 44 manuallymay be adjusted inwardly or outwardly with respect to the wall byrotating the same to cause the collar 40 to screw inwardly or outwardlyon the threaded portion 32 whereby only one stone anchor size isrequired for the job. Thus, the workman can maintain the verticalalignment and installation of the stone courses 14, 16 regardless of theirregularity of the face 12 of the concrete of the building 10, and

without searching for, altering or selecting different sizes of anchors.

In the embodiment shown in FIG. 2, the construction of the stone anchoris substantially the same except for the end portion wherein the splitends and plates 50, 52 have been replaced. This stone anchor in FIG. 2is designated generally by reference numeral and comprises the sameconstruction of member 72 with head 74 and threaded portion 76 as in theprevious construction as well as the collar 78 which has the flat plate80 attached thereto. In lieu of the flat plates 50, 52 of the previousembodiment there is a perpendicular pin 82 extending through the plate80 and attached thereto either by integral fabrication or by welding orsome other means of attachment so that there are in effect two pins 84,86 one on each side of plate 80 and each pin 84, 86 extends into arespective kerf 54, 56 on the courses of stone 14, 16 in the same manneras the plates 50, 52 of the previous embodiment. The adjustment of thestone anchor 70 is the same.

While I have shown and described two embodiments of my stone anchor thisis by way of illustration only since there are various other forms ofthe present invention because various alterations, changes, deviations,amendments, omissions, additions, changes and departures may be made inthe form shown without departing from the scope of my invention asdefined by proper interpretation of the appended claims.
